The D38999/26JJ43SA is a type of circular electrical connector which is commonly used in a variety of industries. This type of connector is available as mil-spec “military specification” as well as commercial grade. This article will look at the application fields and working principle of the D38999/26JJ43SA connector.

Application Fields

The D38999/26JJ43SA connector is a multipin connector which can have up to twenty-one contacts in each of two mating sets, and can support a variety of contact types and sizes. This makes them suitable for a range of applications, from signal, power and coaxial connections to environmentally sealed applications.

The multipin design of the connector makes them popular for large power requirements, such as those needed for high power systems in military vehicles. The connectors can also be used for avionics applications, and can withstand extreme environmental conditions. In industrial applications, the connector can be used for heavy-duty cabling, and is often the preferred choice for robotic, computer automation and motion control systems.

Working Principle

The D38999/26JJ43SA connector is a circular electrical connector with a threaded coupling system. The two mating sets of the connector have a series of precision-machined surfaces and grooves on the circumference of each. When the two halves are mated together, these surfaces and grooves come into contact and form the connection between the two mating sets. This creates a reliable and secure electrical connection.

The connector is also designed with a locking system which ensures that the connection will not be dislodged during vibration or shock. The locking system consists of a series of spring-loaded pins which fit into the grooves of the connector halves when they are mated together. The pins are held securely in place by a metal tang which is bent around the circumference of the connector. This provides an extra layer of security, and helps to ensure that the connection remains secure even in extreme conditions.

The connector also has a waterproof sealing system which prevents moisture and debris from entering the joints between the two sets of contacts. This ensures that the connection remains free of contamination and interference which can cause short circuits.

The D38999/26JJ43SA connector is also designed to be robust and durable, and has a longer operational life compared to other connectors. This makes it suitable for a wide variety of applications, and has become a popular choice for a range of industries.
